Annie Dale Biddle Andrews (born December 13, 1885 – died April 14, 1940) was an important American mathematician. She made history as the first woman to earn a Ph.D. (a very high university degree) in mathematics from the University of California, Berkeley.

Annie Andrews' Early Life and Studies

Annie Dale Biddle was born in Hanford, California. She was the youngest of seven children in her family.

Becoming a Math Whiz

Annie loved learning and went to the University of California. She earned her first degree, a Bachelor of Arts (B.A.), in 1908.

She continued her studies and wrote a special paper called a "thesis" in 1911. This paper was about a complex math topic: Constructive theory of the unicursal plane quartic by synthetic methods. Her university published it in 1912.

Her teachers, Derrick Norman Lehmer and Mellen Haskell, helped her a lot with her research. Her work on "unicursal plane quartics" was very helpful in mathematics at the time. It helped mathematicians understand different types of algebraic shapes.

Teaching and Research

After finishing her studies, Annie started teaching. From 1911 to 1912, she was a math instructor at the University of Washington.

In 1912, she married Wilhelm Samuel Andrews. Even after getting married, she kept working in mathematics.

From 1915 to 1932, she taught math at the University of California. She had first been appointed as a teaching fellow there in 1914.

Annie also shared her new discoveries with other mathematicians. In March 1933, she gave a presentation at a meeting of the Journal of the American Mathematical Society in Palo Alto, California. Her paper was titled "The space quartic of the second kind by synthetic methods". A short summary of her paper was published later that year.

Annie Andrews' Personal Life

Annie Andrews was not just a brilliant mathematician. From 1936, she also became very interested in helping her community. She spent time on public affairs and charity work, alongside her math research.

Annie passed away on April 14, 1940, after being ill for two years. She left behind her husband and their two children. Her contributions to mathematics and her pioneering spirit continue to inspire many.
